Title: Demodulation circuit
Inventor: NODA TSUTOMU
IPC: H03D7/16
Filed: 1984-10-05
Abstract: PURPOSE:To secure the stable demodulation with a both-side band wave signal having suppressed carrier wave by providing a reference oscillator equivalent to an intermediate frequency and detecting the difference of phase between the intermediate frequency and an input frequency by a COSTAS loop system to feed said phase difference back to a local oscillator together with a loop filter. CONSTITUTION:The signal applied to an input terminal 1 is converted into the 2nd intermediate frequency and supplied to the 1st and 2nd phase detectors 7 and 8 via a band pass filter 6 for comparison with the output of a reference oscillator 9 and a signal underwent a 90 deg. phase shift through a 90 deg. phase shifter 10 respectively. The output of both detectors 7 and 8 are added to a multiplier 19 for execution of multiplication, and the output of this multiplication is fed back to the 2nd local oscillator 4 via a loop filter 18. As a result, the 2nd intermediate frequency is used to the oscillator 9 to secure the stable characteristics.

Title: Semiconductor integrated circuit device and its manufacture
Inventor: MITANI SHINICHIRO
IPC: H01L29/78
Filed: 1988-08-24
Abstract: PURPOSE:To make fluctuation of a threshold and punch-through hard to occur and to advance short channel realization of a MISFET by controlling the threshold of the MISFET by the N-type impurity to form a polycrystalline silicon film and the second semiconductor region. CONSTITUTION:N-type impurity As or Sb is used for the impurity 7 to adjust a threshold. For this reason, in an N-channel MISFET region, the depth of the junction between an N<-> or N-type region 7 formed by the impurity 7 and a P<->-well region 3 becomes about 0.05mum, and the junction part between the region 3 and the well 3 never further enlarges the part that the extension of a depletion layer in a drain region is large. Accordingly, it ceases to generate the punch-through between a source and a drain and the change of a threshold. Also, in a P-channel MISFET, as the impurity 7 to adjust the threshold and the N<->-well region 2 are the same conductivity type, P-N junction is never formed in the channel region, and it never accelerates the extension of the depletion layer in the drain region.

Abstract: PURPOSE:To increase an allowable load, by a method wherein the shape of a tooth is formed such that the radius of curvature of the tooth root of an involute gear is increased, a contact area is set to a high value, and the pressure of a contact surface is decreased. CONSTITUTION:An arc of a circle GH of a radius R1 of curvature is drawn centering around a contact F of an involute curve Q with a base circle P, and a tangent line 1C is drawn so that a tangent line JG and a distance (r) between a contact I and a contact C are equal to the R1. An arc of a circle CF ranging from the contact C to the contact F is drawn with the radius R1 centering around the contact I, and a particular tooth shape, formed in combination of the involute curve Q and an arc of a circle having the radius R1 of curvature, is formed. This sets the pressure of a contact surface to a high value through increase of a radius of curvature, which is decreased at a tooth root part, decreases a surface pressure, and enables an allowable load to be set to a high value relative to a gear of the same size.

Filed: 1983-11-09
Abstract: PURPOSE:To enable to regulate precisely ultrafine rotation with a simple and low power consumption power construction by altering the polarizing directions of a piezoelectric element by half, and attaching electrodes to the two opposite surfaces which is perpendicular to the polarizing axis. CONSTITUTION:The front and back halves A, B of a piezoelectric element 1 are polarized so that the polarizing directions become reverse in lateral direction, and electrodes 2 are attached to the two opposite surfaces perpendicular to the polarizing axis. When positive and negative electric fields are applied to the electrodes 2 of upper and lower surfaces, the right and left sides of the front half A are deflected upward. Accordingly, a clockwise rotary force is acted in the upper half, and a counterclockwise rotary force is acted in the lower half. The distortion due to the rotary force is proportional to the applied voltage, and when the voltage is removed, it is returned to the original position. When the phase is altered, a distortion occurs in the reverse direction, and in case of AC signal, it is vibrated in both directions.

Title: Automatic threshold value control circuit
Inventor: OKABAYASHI NAONORI
IPC: H03K5/156
Filed: 1987-08-21
Abstract: PURPOSE:To obtain a reproduced wave without duty distortion by detecting a peak of a signal amplified by an amplification factor different from that of a main signal from an input signal and using the result as a threshold value. CONSTITUTION:The amplification factor of the amplifier 1 amplifying the input signal A is lowered so as to be operated at the nonsaturation region. The other output of the amplifier 1 is given to a peak detection circuit and the output of the peak detection circuit is given to a comparator 3 as a threshold level D. The ratio of the amplification factor of the amplifier 4 and the amplification factor of the amplifier 2 is decided in a way of which height of the amplitude of the input signal the threshold level is to be selected in order to obtain a reproduced waveform close to that of the original signal. Thus, even when the amplifier of the main signal is saturated and the waveform is distorted, the threshold value setting circuit is not saturated at a conventional wider input signal level and generates a normal threshold voltage, then the reproducing signal without duty distortion is outputted even when the main signal is saturated.
